So I have a 33 gallon tank that I want to set up as a divided tank for the new betta's I'm getting, but I'm worried about them getting stressed out. The dividers won't be see through but the will be sharing the same water, will the males stress because the know a female is near or will they be fine?
Thanks

I've heard many people say the the "spawning hormones" make it bad to keep them in the same divided tank, but others who have had great success with keeping them in the same divided tank. I don't know, I guess you could try it and keep an eye on them. Just make sure there is no way for them to wiggle or jump to the other side!

i was thinking for a bit about doing this, instead of dividing my soon-to-be 10 gallons with Cup and Zidane, and Lulu and Chappy, but then i thought about how they could 'smell' each other all the time, and i don't want them stressing. ;A;

I kep a male and a female like this for 5 months no problems the male would flare at her she would swim away then hide and watch him they were both fine i just had quite a few plants up against the divider
